Abstract

A process heat exchanger (PHE) in a nuclear hydrogen system is a key component for transferring the considerable heat generated in a very high temperature reactor (VHTR) to a chemical reaction that yields a large quantity of hydrogen. A performance test on a small-scale PHE prototype made of Hastelloy-X is underway in a small-scale gas loop at the Korea Atomic Energy Research Institute. Previous research on the high-temperature structural analysis of the small-scale PHE prototype had been performed using base material properties. In this study, a high-temperature structural analysis considering the mechanical properties in the weld zone was performed, and the obtained results were compared with those of the previous research.

수소를 대량으로 생산하기 위한 원자력수소생산시스템에서 공정열교환기는 초고온가스로로부터 생성된 초고온 열을 화학반응공정으로 전달하는 핵심기기이다. 한국원자력연구원에 구축되어 있는 소형가스루프에서 Hastelloy-X 로 제작된 소형 공정열교환기(PHE) 시제품에 대한 성능시험이 수행되고 있다. 그동안 소형 PHE 시제품에 대한 고온구조해석은 용접부의 기계적 물성변화를 고려하지 않은 해석이 주로 수행되었다. 본 연구에서는 계장화 압입시험으로부터 얻은 용접부 기계적 물성치를 이용하여 고온구조해석을 수행하고 그 결과를 분석하였다.
